Mazda FP engine
Content
Mazda FP engines are modifications of FS engines with a reduction in their size. The technique is very similar to the FS in terms of design, but features an original cylinder block, crankshaft, as well as pistons and connecting rods.
FP engines are equipped with a 16-valve head with two camshafts located on top of the cylinder head. The gas distribution mechanism is driven by a toothed belt.
The motors are equipped with hydraulic lifters. Engine ignition type is "distributor". There are two types of FP engines - a 100 or 90 horsepower model. The compression power of the latest model reaches 9,6: 1, it differs in the firmware and the diameter of the throttle valve.
The Mazda FP has excellent functionality and is robust enough. An engine can travel over 300 kilometers with regular maintenance and only good quality lubricants and fuels. In addition, the Mazda FP engine can be completely overhauled as it is subject to overhaul.

Mazda FP engine design
The four-stroke, 16-valve petrol engines are equipped with four cylinders and an electronically controlled fuel injection system. The engine has a longitudinal cylinder with pistons. The crankshaft is common, its camshafts are placed on top. The closed engine cooling system runs on a special fluid and maintains forced circulation. A combined engine lubrication system is suitable for FP.

FP motor maintenance
- Change of oil. The interval of 15 thousand kilometers is the rate of oil change intensity for Mazda cars of the Capella, 626 and Premacy models. These cars have engines of the FP type, with a size of 1,8 liters. Dry engines can hold up to 3,7 liters of engine oil. If the oil filter changes during the replacement procedure, the oil needs to be poured exactly 3,5 liters. If the filter is not replaced, 3,3 liters of engine oil is added. API oil classification - SH, SG and SJ. Viscosity - SAE 10W-30, which means off-season oil.
- Replacing the timing belt. According to the maintenance regulations, this procedure must be carried out at an interval of once per 100 kilometers of the vehicle's run.
- Replacing spark plugs. The candles must also be replaced once every 30 kilometers. If platinum plugs are installed in the engine, they are replaced every 000 kilometers. For Mazda FP engines, the recommended spark plugs are Denso PKJ80CR000, NGK BKR16E-8 and Champion RC5YC models.
- Replacing the air filter. This part must be replaced every 40 kilometers the vehicle has traveled. The filter must be checked every 000 kilometers.
- Replacing the cooling system. The coolant is changed in the engine every two years and is filled into a special container with a capacity of 7,5 liters.

User Reviews
Ignat Aleksandrovich, 36 years old, Mazda 626, 1996: I received a used foreign car on order, the car has been perfectly preserved since the 90s. A good 1.8 - 16v engine was in average condition, I had to replace the spark plugs and sort it out. It is easy to do it manually, you just need to memorize the fixing schemes for parts and fuel lines. I would like to note the good quality of the revised engine.
Dmitry Fedorovich, 50 years old, Mazda Capella, produced in 2000: I am generally satisfied with the FP engine. Taking a used car, I had to sort out the engine and change the fuel filters, as well as consumables. The main thing is to control the level of engine oil and use only high-quality fuel. Then a car with such an engine will be able to serve for a long time.
